I've never really used a toner before, but it's something I've always been interested in. After a quick read up I found that if you have dry skin then you should use a toner that is a "refreshing toner", so I bought this from The Body Shop. It's £3 for a 60ml bottle, however you can only buy the 200ml version online which is priced at £8.
I can't compare this to other toners, but I'll explain my experience with the product. The toner itself is quite thick, a bit like a runny gel, and you apply it to your face after cleansing using a cotton pad or something similar. I use red towels to pat my face dry, and every time I've used this toner I've found it picks up teeny tiny bits of towel fibers from my face which I didn't know were on there! I'm not sure if I've noticed any other difference with regards to pores or anything, but it has made my face feel softer at night.
I don't think I'll be buying this again as I haven't had any miracle effects, but to be honest, I think this bottle will last me a good month or two, so it's value for money!
